R O A D C A RT SPECIFICATION forming part of Letters Patent No. 428,921,dated May 27, 1890.

Application filed January 31, 1890. Serial No. 338,821- (No model.)

To all whom it may concern:

Be it known that 1, JAMES II. LEWIS, a citizen of the United States,residing at Detroit, in the county of IVayne and State of Michigan, haveinvented certain new and useful Improvements in Road-Carts, of which thefollowing is a specification,reference being had therein to theaccompanying drawings.

This invention relates to new and useful lll'lplOYGllIGlltS inroad-carts; and the invention consists in the peculiar vconstruction ofthe seat and seat-support, whereby the horse motion is dispensed withand a more comfortable and efficient device is made, as hereinafter morefully described.

In the drawings which accompany this specification, Figure 1 is a rearelevation of my improved cart. Fig. 2 is a vertical central longitudinalsection thereof. Fig. 3 is an enlarged cross-section on line 50 0c inFig. 2. Fig. 4. is a detached perspective view of the bearing for theseat.

A are the wheels. B are the shafts. O is the axle. D is the cross-bar. Eis the semielliptic spring which is clipped to the axle. These parts areof well-known and usual construction.

F is the seat, which is pivotally supported upon the spring E by meansof the U-shaped seat-supporting bracket G", secured at its upper ends tothe seat and at its lower bent portion pivotally secured to the block IIbeneath the caps H, clipped upon the spring E, there being anintermediate block I between the block II and the spring. The seat isprovided at each side with the side pieces J, which on their lower edgeare preferably out into segmental circular shape, as at K, which movesover the corresponding segmental face L, formed upon the block M at therear end of the seat-bar N, which bars are pivotally connected at theirforward ends to the cross-bar D. The block M is provided with adownwardly-projecting ear a, pivotally connected to the supporting-armsZ), which at their lower ends are secured to the block I upon thespring.

0 are spring-plates secured on the inner side of the blocks M, andpreferably of segmental circular shape, having the ears or lugs dprojecting inwardly at their ends. To these lugs are preferably securedthe rod c, which passes through a suitable aperture in the bracket G,and over which are sleeved the spiral springs fone on either side of thebracket Gbearing with one end against the bracket and at the other endagainst the lugs (Z. This bracket is made adjustable upon the block M bymeans of the bolts g, engaging into the slots h. This adjustment doesnot change the tension of the springs upon the seat-supportingbracketD,but simply changes the angle at which the seat will normally stand inrelation to the spring.

0 is a foot rest or ciate,which consists of the usual curved barssecured at their rear ends to the under side of the seat, connectedtogether by slats. At their forward ends I preferably leave them free,or I may connect them bya strap P to the cross-bar to prevent theirbeing depressed too far when the driver steps in or out, when his wholeweight is sustained thereby. This strap is made adjustable, so that itmay be lengthened or shortened to suit the convenience of the driver.

In practice, when the driver occupies the seat, as it is not rigidlyconnected in any way with the shaft, the horse motion in the shafts andthe seat-bars is communicated to the seat only through the medium of thesprings f, and the weight of the rider acting against the springs checksany oscillation of the seat.

The horse'motion which is transmitted to the rider through the seat-barsin previous constructions has no effect in my cart, as the seat-barshave no connection with the shafts or cross-bars.

That I claim as my invention is 1. In a road-cart, the combination, withthe seat and the seat-supporting spring, of an oscillatingseat-supportin g frame mounted upon said spring, and of check-springsapplied to said frame to counteract the oscillation thereof,substantially as described.

2. In a road-cart, the combinatiomwith a seat mounted on oscillatingsupports to have a free play in the longitudinal direction of the cart,of check-springs applied thereto to counter act the oscillations,andofseat-bars supported independently of the seat and holding suchcheck-springs in position, substantially as de scribed.

In a road-cart, the Combination, with a supporting-frame pivotallymounted upon a seat-supporting spring and carrying the seat free tooscillate in the longitudinal direction of the cart, of check-springs onopposite sides of the seat and engaging with the oscillating sup portsto check their motion, substantially as described.

4. In a road-cart, the combination, with the seat and theseat-supporting spring, of an oscillating seat-supporting frame mountedupon said spring, of check-spring applied to said frame, and ofadjusting devices for said spring, substantially as described.

5. In aroad-cart, the combination, with the seat and the seat-supportingspring, of the supports G, interposed between and pivotally supportedupon said spring, the cheek-springs, which hold said supports inposition, the independent seatbars, to which said checksprings aresecured, and the supporting-frame under the rear end of said seat-bars,substantially as described.

0. In a road-cart, the combination of the seat-supporting springs, theoscillating seatsupports pivotally supported thereon, the

checksprings, which hold it in position, the independent seat-bars, towhich said springs are secured, and the circular bearings between suchseat and seat-bars, substantially as described.

'7. In a road-cart, the combination, with the springs, of the U-shapedseat-supports G, the seat-bars hinged at their forward ends, thestandards b, pivotally supporting the rear end of the scat-bars, thesegmental circular faces K and L, and the check-springs f, sleeved uponthe rod a, substantially as described.

S. In a road-cart, the combination, with an oscillating seat-framemounted upon the scatsupporting springs, of check-springs to counteractthe oscillations of said frame, and of the foot-rest secured only tosaid seat, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses,this 10th day of December, 1880.

JAMES H. LEWIS.
